I suppose the same could still be said for a zoom climbing fighter trying to hit HVA's...
what was that tactic eagle drivers call.. wall of eagles... stacked on top of each other.. to protect against such attempts??
It was something we practiced often in the F-15 simulator, called the "high-fast flyer" intercept. The target was always a MiG-25 or 31, at 60,000 feet+ and mach 2.5 or so. The AIM-7 had weak kinematics compared to the AIM-120, so the profile has probably changed, but essentially, it went something like this, starting from maybe 45,000 feet:
1) Jettison ALL external fuel tanks.
2) Go full AB and leave it there.
3) Accelerate to mach 2+ or as fast as it'll go
4) Begin the climb so as to place the HUD steering cue for the missile in the best possible geometry.
This is from an F/A-18 but the display is similar. The circle expands and contracts based upon the overall geometry of the shot. The dot (lower right) needs to be inside the circle, optimally right in the middle. This sets the jet up for an optimum shot. We'd pull a bit harder to put the dot slightly lower in the circle.
Topping out above 60,000 feet, we'd always pickle 2 or 3. Again, with the AIM-120, it's probably different and much easier.
We weren't supposed to practice this outside the simulator, because in peace time, flight above 50,000 feet required a pressure suit (full or partial) - decompression above 50,000 feet is often fatal because of
severe evolution of nitrogen gas in the body... the bends.
But we'd go above 50,000' on occasion, just because it was cool. The sky is partially blackened, and if you have a crisp horizon, you really can see the Earth curvature. Just barely, but it was there.
